How to scan a document on Xiaomi: all ways with settings and examples

Scanning documents via Xiaomi’s smartphone is a quick way to digitize receipts, passports, diplomas or contracts without using a cumbersome scanner. Depending on the model (Redmi Note 12, POCO X5, Xiaomi 13T, etc.) and the MIUI version, there are several built-in and third-party tools available, from the basic mode in the Camera app to specialized services like Google Drive or CamScanner. But how to choose the best method to get a clear PDF without distortion? And why on some devices the feature is hidden in non-obvious menus?

This article is a review of all the current methods of scanning on Xiaomi, taking into account the features of the firmware, comparing results (see the table below) and step-by-step instructions from the photo. And also answers to frequent questions: how to fix blur, reduce the size of a file or scan a multi-page document. If you need to send a scan by mail or save it to the cloud, here you will find working life hacks.

1. Built-in "Document" function in the Camera app

The easiest way is to use Document Mode in the standard Camera app. It is available on all Xiaomi smartphones with MIUI 12 and later (including Redmi and POCO). The algorithm automatically aligns perspective, removes shadows and saves the result in.pdf or.jpg format.

To activate the mode:

• 📱 Open the Camera app on your Xiaomi.
• 🔍 Scroll through the shooting modes left to the Document item (on some models it is hidden under the Document).
• 📄 Point the camera at the document, the frame will automatically circle the boundaries. Press the descent button.
• ✅ Confirm the result or click Remove if the quality is not satisfied.

The finished scan is saved in the gallery in the Scanned Documents folder. From there it can be sent by mail, to the messenger or uploaded to the cloud. On devices with a Snapdragon 8 Gen 2 processor (for example, Xiaomi 13 Ultra), the mode supports scanning in resolution up to 12 MP with automatic color correction.

⚠️ Note: If Document Mode is not in the camera menu, update the app via Google Play or check your settings MIUI: Settings → Annexes → Application management → Camera. → Update.

2. Scanning through Google Drive: The Cloud Way

If you need to save the scan in the cloud immediately, use the built-in scanner in Google Drive. This method is suitable for Xiaomi owners with pre-installed Google services (on the Chinese firmware may not be available), the advantage is automatic synchronization and the ability to edit text through Google Docs.

Instructions:

1. Open the Google Drive app on your phone.
2. Press + → Scan (the scanner icon in the lower right corner).
3. Take a picture of the document. Drive will automatically trim the edges and improve contrast.
4. Click Save – the file will appear in the My Discs section in.pdf format.

For multi-page documents, repeat step 3 – Drive will combine all pages into one PDF. Less method: scan quality depends on the lighting, and on budget models Redmi (for example, Redmi A2) can sag the detail.

3 Third-Party Apps: CamScanner and Adobe Scan

For professional scanning with OCR-recognition of text and advanced color settings, use specialized applications. Xiaomi works well:

• 📑 CamScanner – supports cloud storage, automatic pruning and export to.docx.
• 📄 Adobe Scan – Integration with Adobe Acrobat, high detail when scanning small text.
• 🖼️ Microsoft Lens – Optimized for Office 365, Free.

Example of settings in CamScanner:

1. Install the app from Google Play.
2. Open it and press Scan.
3. Select Document Mode and take a photo of the sheet.
4. In the editor, adjust Color (black and white for text), Contrast and Sharpness.
5. Save as PDF or export to Google Drive.

Tip: In CamScanner settings, disable Watermarks (Settings → Watermark) to avoid advertising tags on the free version.

💡

If the scan is blurry, try turning on Professional in the camera settings and manually setting ISO to 100-200 and shutter speed to 1/125, which will reduce noise on Redmi's budget models.

4. scanning through MIUI Notes (Notes)

Little-known life hack: app Notes in MIUI It can scan documents and save them inside a note, which is useful if you want to fast-track a scan to a text comment (for example, for work or study). MIUI 13+.

How to use:

1. Open Notes (notebook icon on the main screen).
2. Create a new note and click on the + → Scan the document icon.
3. Take a picture of the sheet. The app will automatically cut the edges.
4. Save the scan inside the note or export it through Share.

Limitation: The quality is worse than in specialized applications, but it is sufficient for household tasks, suitable for scanning checks, schedules or short letters.

⚠️ Note: On some firmware (for example, MIUI for global market) scan feature in Notes may not be available. Check app updates in Google Play.

5. Scanning of multipage documents

If you want to digitize a document into 10+ pages (such as a contract or book), use applications that support batch scanning:

• 📚 CamScanner: Packet scanning mode → Take pictures of pages in a row, then click Ready to combine into one PDF.
• 📖 Adobe Scan: Automatically detects the page and suggests adding a new one after each frame.
• 📑 Microsoft Lens: Supports up to 50 pages in a single session.

On Xiaomi with powerful processors (Snapdragon 8+ Gen 1 and later), batch scanning works without lags. On budget models (Redmi 10A), processing delays are possible - in this case, scan 3-5 pages at a time.

6. Scan optimization: file size and quality

By default, PDF scans weigh 1 to 5 MB, but this size can be reduced without loss of quality.

• 📉 In CamScanner: When exporting, select Average Quality (size will decrease by 40-60%).
• 🖼️ In Google Drive: After scanning, click More → Squeeze. PDF.
• 🔧 Through the Files (MIUI): find PDF, Press Share. → Squeeze.

To increase clarity:

• 🔍 In Adobe Scan, enable the option to Improve text (OCR).
• 🎨 In the Gallery. MIUI open the scan → Edit → Details.

On devices with a 108 MP camera (for example, Xiaomi 12S Ultra) scans in Document mode can weigh up to 10 MB. To reduce the size, before shooting, switch the camera resolution to 12 MP in the settings.

💡

For official documents (passports, diplomas) always scan in color and with a resolution of at least 300 dpi. Black and white mode is suitable only for text without graphics.
